go tool objdump 反汇编使用说明

将 Go 将二进制文件反编译成汇编代码，同时打印 Go 源码。

go tool objdump usage: go tool objdump [-S] [-gnu] [-s symregexp] binary [start end]    -S    print Go code alongside assembly   -gnu         print GNU assembly next to Go assembly (where supported)   -s string         only dump symbols matching this regexp 

通常用法

go tool objdump -S -s "main.fun1" main 

-S：打印在旁边 Go 源码。

-s ：可选，匹配要打印的具体片段，支持正则表达式。

main：可执行文件的编译。

package main  func main() { 
         example(make([]string, 2, 4), "hello", 10) }  func example(slice []string, str string, i int) { 
         panic("Want stack trace") } 

go build main64.go  go tool objdump -S -s "main.main" main64.exe  TEXT main.main(SB) D:/dev/php/magook/trunk/server/golang/project/demo1/main64.go func main() {
